We would like to inform that the PQQ FA2172 Main Rehab Framework Lot 2 process is being terminated due to a lack of candidates. Lot 2 was structured as a multi-supplier framework with 3 to 5 contractors. Since we received only one Lot 2 PQQ response it is not possible to proceed at this stage with a tender process for Lot 2 that is consistent with the Contract Notice. The limited number of submissions received would additionally not provide the necessary competitive environment required to ensure the best value for money. This decision has been made in accordance with our procurement process, which aims to foster a competitive and fair bidding process. We believe that re-evaluating the scope of the ITN and possibly re-issuing it at a later date may attract a broader range of suppliers and ensure a more competitive process.
